This one is not bad at all, but one or two spots would benefit from a touch-up. But I want to make sure it won't look worse. If nobody has advice I may test a few things out on a dead 38C that's coming (purchased for the accessories - calc has major battery damage).

Try black shoe polish? (Kiwi wax in a metal can)
I used it decades ago on an old bakelite radio, and it still looks good.
